I don't know E, but does this mean that you resend the message to yourself?

So what if the unexpected message is e.g. (on_hook), but the subscriber
simply flashed the hook? Then you might get a rapid (on_hook) - (off_hook)
sequence. Resending (on_hook), then (off_hook) might work, and result in
the same sequence, but what if it doesn't play out that way? Perhaps the
contents of the queue were (on_hook) - (switch_reply) - (off_hook). Now,
you resend (on_hook), then find an expected message, and continue
normally. But now the queue looks like: (off_hook) - (on_hook), which is
not what the subscriber intended.
